The purpose of this invention is to provide a kind of hardness height, the better artificial fiber cutting blade high-abrasive material of wear resisting property.
Technical scheme of the present invention is: the characteristic that adopts cobalt chromium Co-Cr alloy, appropriate design by alloying constituent, on the basis that keeps the Co matrix, fully improve the chromium Cr content of alloy, utilize α-Cr and MC to substantially improve the wear resistance of alloy mutually, keep excellent corrosion resisting performance, further reduced cost of alloy; Its chemical composition content by weight percentage, by 1.8～2.5 parts in carbon, 10～12 parts in nickel, 3～5 parts of molybdenums, 2～4 parts of iron, 24～28 parts of cobalts, 10～12 parts in tungsten, 1.2～2.0 parts of copper, 4～5 parts of niobiums, 0.0001～2 part in manganese, 0.0001～2 part of composition of silicon, surplus is a chromium.
The present invention has following advantage:
The present invention is a kind of regenerated fiber blade that is used to cut, owing to adopt high-abrasive material Cr base, have the advantages that price is low, hardness is high, solidity to corrosion is good, hardness of the present invention can reach 56 to 59, and have the toughness suitable, and have corrosion resistance (erosion rate of 5% sulfuric acid medium is less than 0.03mm) preferably with Stellite 6.
Fig. 1 is a smelting technology route map of the present invention.
Below in conjunction with drawings and Examples the present invention is described in further detail.
The present invention adopts Metal Cr, Co, W, Ni, W, Mo, the Cu of general purity, adopts the normal pressure smelting technology to prepare part, and concrete operational path as shown in Figure 1.
The present invention adopts the characteristic of cobalt chromium Co-Cr alloy, appropriate design by alloying constituent, on the basis that keeps the Co matrix, fully improve the chromium Cr content of alloy, utilize α-Cr and MC to substantially improve the wear resistance of alloy mutually, and kept excellent corrosion resisting performance, further reduced cost of alloy; Its chemical composition content by weight, by 1.8～2.5 parts in carbon, 10～12 parts in nickel, 3～5 parts of molybdenums, 2～4 parts of iron, 24～28 parts of cobalts, 10～12 parts in tungsten, 1.2～2.0 parts of copper, 4～5 parts of niobiums, 0.001～2 part in manganese, 0.001～2 part of composition of silicon, surplus is a chromium.
